How Much Does a Bathroom Renovation Cost in Australia in 2026?
Bathroom reno prices in Australia typically run from $8,000 for a refresh to $40,000+ for a full strip-out. Here's what drives the cost — and how to budget smart.
Wondering how much a bathroom renovation costs in Australia? As a rough guide, a budget refresh typically runs $8,000–$15,000, a mid-range renovation sits around $15,000–$25,000, and a high-end full strip-out usually starts at $25,000 and climbs past $40,000. Where you land depends on the size of the room, whether you move plumbing, how much tiling is involved, and the quality of the fixtures you choose.
These are typical price ranges only — every bathroom is different, and the best way to know your number is to compare a few free quotes from local tradies. Below we break down what you actually pay for, why coordinating trades matters, and how to keep your bathroom reno budget under control.
The quick answer: bathroom renovation cost by tier
Here’s a realistic snapshot of what different levels of bathroom renovation cost in Australia in 2026.
| Renovation tier | Typical cost (AUD) | What you get |
|---|---|---|
| Budget refresh | $8,000–$15,000 | Keep the existing layout; new fixtures, vanity, tapware, paint, possibly re-tiling one area |
| Mid-range renovation | $15,000–$25,000 | Full re-tile, new vanity and toilet, new shower, quality fixtures, minor layout tweaks |
| High-end full strip-out | $25,000–$40,000+ | Complete demolition, new layout, moved plumbing, premium tiles and fixtures, custom joinery |
A small bathroom renovation cost tends to sit at the lower end of each range simply because there’s less floor and wall area to tile and waterproof — but don’t assume small means cheap. A compact ensuite with the plumbing moved and premium finishes can easily cost more than a larger, simpler main bathroom.
What drives the cost to renovate a bathroom
Two bathrooms of the same size can differ by $15,000 or more. These are the biggest factors.
Room size and tiling area
Tiling is one of the largest line items in most renovations, and it scales with your floor and wall area. Full floor-to-ceiling tiling costs significantly more than a half-height tile with painted walls above. Larger-format tiles, mosaics, and feature walls all add labour and material cost. If you want to understand tiling pricing in detail, our tilers service page is a good place to start.
Whether you move the plumbing
Keeping the toilet, shower, and vanity in their existing positions is one of the single biggest ways to save. The moment you relocate a drain, waste, or water point, you add plumbing labour, potential floor work, and often extra waterproofing. Moving plumbing is where budgets quietly blow out, so weigh up whether a new layout is truly worth it. See our plumbers service page for more on what’s involved.
Fixture and finish quality
The gap between builder-grade and premium fixtures is enormous. A basic vanity, toilet, and tapware package might total a couple of thousand dollars; a designer freestanding bath, frameless shower screen, imported tiles, and premium tapware can add ten thousand or more on their own. Your fixture choices are the easiest lever to pull when balancing your bathroom reno budget.
Structural and hidden surprises
Once the walls are opened up, older homes can reveal water damage, rotten timber, outdated wiring, or non-compliant plumbing. A sensible reno budget includes a contingency of 10–15% for the things nobody can see until demolition begins.
The trades involved in a bathroom renovation
A bathroom is one of the most trade-dense rooms in the house. A typical renovation involves several specialists, and getting them in the right order is critical.
- Plumber — rough-in and fit-off for the toilet, shower, vanity, and any relocated pipework.
- Waterproofer — applies the certified waterproof membrane before tiling (more on this below).
- Tiler — prepares surfaces and lays floor and wall tiles.
- Electrician — wiring for lights, exhaust fans, heated towel rails, and power points.
- Builder or carpenter — demolition, wall framing, sheeting, niches, and custom joinery.
- Plasterer and painter — patching, sheeting, and finishing.

Why coordinating trades matters
The trades above have to follow a strict sequence. Waterproofing must be finished and cured before tiling starts. Plumbing and electrical rough-in must happen before walls are closed up. If one trade runs late, everyone behind them stalls — and delays cost money.
This is why coordination is so important. Some homeowners hire a builder to project-manage the whole job, while others manage the trades themselves to save on margin. If you’re self-managing, lining up reliable, available tradies in the right order is the difference between a three-week reno and a three-month one. Posting your job on Tradies Club lets you line up multiple trades from local professionals who can quote and schedule around each other.
Waterproofing: the cost you should never cut
Waterproofing is one of the smaller line items by dollar value, but it’s the most important. In Australia, bathroom waterproofing must be carried out to the relevant Australian Standards and, in most states, completed or certified by a licensed waterproofer. A failed membrane can lead to leaks, structural damage, mould, and a repair bill many times larger than the original job.
Typical waterproofing cost for a standard bathroom generally falls in the low thousands, depending on the wet areas and floor area covered. Always confirm your waterproofer provides the required certification — it protects your home and is often needed for insurance and future sale. Cutting corners here is the one place a cheap quote can cost you dearly.
Sample cost breakdown by line item
To show where the money goes, here’s an indicative breakdown for a mid-range main bathroom renovation. These are typical ranges only and will vary by state, home, and finish.
| Line item | Typical range (AUD) |
|---|---|
| Demolition and rubbish removal | $1,000–$2,500 |
| Plumbing (rough-in and fit-off) | $3,000–$6,000 |
| Waterproofing (certified) | $800–$3,000 |
| Tiling (supply and lay) | $4,000–$9,000 |
| Electrical | $1,000–$2,500 |
| Fixtures and fittings | $3,000–$8,000+ |
| Carpentry, plastering and painting | $1,500–$4,000 |
Add these up and you can see how a mid-range job lands in the $15,000–$25,000 band — and how quickly premium tiles, a moved layout, or high-end fixtures push a project into high-end territory.
How to keep your bathroom reno budget on track
- Keep the existing layout where you can — not moving plumbing is the biggest single saving.
- Choose smart on fixtures. Spend on the pieces you touch daily (tapware, shower) and save on the ones you don’t.
- Tile to a sensible height. Full floor-to-ceiling tiling looks great but costs more than a well-chosen half-height.
- Build in a contingency of 10–15% for hidden surprises.
- Compare multiple quotes. Prices for the same job vary widely between tradies — comparing free quotes is the simplest way to avoid overpaying.

Frequently asked questions
How long does a bathroom renovation take?
Most bathroom renovations take two to four weeks once work begins, depending on complexity and how well the trades are coordinated. Waterproofing needs time to cure before tiling, and delays between trades are the most common cause of overruns.
How much does a small bathroom renovation cost?
A small bathroom renovation cost usually sits at the lower end of each tier — roughly $8,000–$15,000 for a refresh — because there’s less area to tile and waterproof. That said, moving plumbing or choosing premium finishes can push even a small ensuite well beyond that.
Do I really need a certified waterproofer?
Yes. In Australia, bathroom waterproofing must meet the relevant Australian Standards and, in most states, be carried out or signed off by a licensed professional. It protects your home from water damage and is often required for insurance and resale.
Is it cheaper to renovate or move fixtures around?
Keeping fixtures in their existing positions is almost always cheaper. Relocating a toilet, shower, or vanity adds plumbing labour and extra waterproofing, so only move plumbing when the improved layout is genuinely worth the added cost.
